Abstract: Pineapple materials sourced from agricultural waste have been employed to process novel bio-degradable rigid composite films. The matrix for the films consisted of flour extracted from pineapple stem, known for its high amylose and amylopectin content, while the additive comprised of polyvinyl alcohol and polyethylene glycol starch-based materials have been widely studied and developed for commercial production, primarily from corn and tapioca. In order to reduce our dependence on nonrenewable plastics and solve the problem of nonbiodegradable plastic waste, there has been much attention paid to the development of biodegradable plastics from natural resources. However, the use of these starches could generate food security problems. Therefore, the use of alternative starch sources, such as agricultural waste, would be of great interest. In this work, we investigated the properties of films prepared from pineapple stem , which has a high amylose content. was formed enabled by using a doctor blade coating method. transformation of flour solution into films sheets, In this study was used the condition following: the mixture was stirred at 80 the film thickness is 0.5 mm. consequently, the flour film composite exhibited exceptional mechanical properties, boasting a modulus within the range of 1.90 ± 0.11 MPa to 98.98 ± 1.63 MPa and a strength of 5.42 ± 0.15 MPa to 1.44 ± 0.58 MPa. notably, their stretchability remained relatively modest, spanning from 242.35 ± 1.35 % to 1.56 ± 0.59% the films demonstrated a water vapor transmission rate (WVTR) of approximately 178.46 ± 6.53 to 408.98 ± 40.60 of their own weight without disintegration. Tailoring the mechanical performance of the films composite was achieved by manipulating the PEG content,15 wt%. Phase morphologies of the flour films unveiled a uniformly distributed microstructure without any observable flour particles. The findings highlight the potential of flour for pineapple waste materials for producing sustainable bio-degradable foams with desirable properties and contribute to the field of sustainable materials.
